Firmware for the Teclast X89 Kindow tablet, which has an unusual 1440x1080 screen resolution.

I found the firmware by searching for the model number "D5N3" on the Teclast Support Site, which led me to a OneDrive folder with Android and Windows images. I used PowerShell in a Windows VM to mount the 'install.wim' install file and found the file SileadTouch.fw in Windows\System32\drivers.

I found the parameters by trial-and-error with the gsl1680-acpi driver, and this firmware has been tested with that driver and the parameters listed here:

Axis swapped
X-axis flipped
Width: 860
Height: 1660

I have not prepared a patch for the silead_ts firmware and I don't think I'll have time to figure that process out anytime soon.

Hi @werkshy - thanks for your contribution.

Since you found the whole Windows driver package for this device, would you mind adding the other files to the PR?
It's not a main focus of this repository, but considering that many cheap tablet manufacturers aren't very interested in providing long-term support, I think it can't hurt to collect these as well.
